A series of “guava-like” silica/polyacrylate nanocomposite particles with different grafting degrees were prepared via mini-emulsion polymerization. The silica/polyacrylate composite particles were melt-mixed with unfilled polyacrylate (PA) resin to prepare the corresponding silica/polyacrylate molded composites, and the dispersion mechanism of these silica particles from the “guava-like” composite particles into polyacrylate matrix was studied by the section transmission electron microscope (TEM) micrographs of silica/polyacrylate molded composites. It was found that the grafting degree of silica particles played a crucial role in the dispersion of silica/polyacrylate composite particles into the polyacrylate matrix.
